storing VSX register pairs. This patch also adds the VSRp register class
definition needed for these instructions.

Rename `future*` encoding test files to include ISA3.1 in the file name
and combine with exisitng ISA3.1 instruction encoding tests that were
added into `p10*` test files.
Keeping the `p10*` files for now to ensure we don't add more to it.
Will remove once all ISA3.1 instruction are implemented.

This patch is to add the InstAlias definitions for MTSPR8/MFSPR8,
and add the some new mtspr/mfspr InstAlias we may use.

A previous patch should have added pld and pstd and any support code in
the backend that is required for prefixed load and store type operations.
This patch adds a number of additional prefixed load and store type
instructions for the future CPU.
Differential Revision: https://reviews.llvm.org/D72577
Add the prefixed instructions pld and pstd to future CPU. These are load and
store instructions that require new operand types that are 34 bits. This patch
adds the two instructions as well as the operand types required.
Note that this patch also makes a minor change to tablegen to account for the
fact that some instructions are going to require shifts greater than 31 bits
for the new 34 bit instructions.
Differential Revision: https://reviews.llvm.org/D72574
Future CPU will include support for prefixed instructions.
These prefixed instructions are formed by a 4 byte prefix
immediately followed by a 4 byte instruction effectively
making an 8 byte instruction. The new instruction paddi
is a prefixed form of addi.
This patch adds paddi and all of the support required
for that instruction. The majority of the patch deals with
supporting the new prefixed instructions. The addition of
paddi is mainly to allow for testing.

The Overflow version of XO-Form instruction uses the SO, OV and
OV32 special registers.
This changes modifies existing multiclasses and instruction
definitions to allow for the use of the XER register to record
the various types if overflow from possible add, subtract and
multiply instructions. It then modifies the existing instructions
as to use these multiclasses as needed.
